This is my first post so will try and keep things to the point! - any advice would be much appreciated 
When DS was about 2 weeks he came out in a bad rash on his face and chest/back. He also had bad gas and explosive nappies and diarrhoea. Cows milk allergy was queried and we quickly started on a dairy free diet for me as I was breastfeeding and nutramigen for the one bottle he had at nighttime. His symptoms improved almost immediately and so we continued. My supply dwindled and so we headed over to completely bottle fed in about 4 weeks after that.
Although there was no definitive start date (about 6/7 weeks)I was aware DS wasn't feeding that well with me or the bottle and was unsettled after and seemed hungry so I started to keep a note of amounts. I went to the doctor who thought silent reflux and started us on milk thicker and ranitidine. No joy. About a week after this he was almost entirely refusing to eat (11 weeks) We ended up in hospital over night and we were assured it was reflux and put on a higher dose of ranitidine and gaviscon. No joy. DS will still only take 2/3 oZ's max per feed, a total of 20 per day. About 15 less than he should be taking for his weight (so I was told by doc and HV). So then dietician put us on neocate to see if there was still some allergy taking place but a week in and there's no improvement (I've been assured that any taste aversion would last a couple of days tops and then instinct to eat would take over)
Although DS is putting weight on every week it's a v small amount and he's now crossing lines on the percentile chart. I saw a paediatrician yesterday who practically patted me on the head and told me 'babies cry for lots of reasons' and they 'take a while to find their 'line''
I left crying. I know my baby and I know he's hungry. He's constantly crying, gnawing on his fist, my shoulder, his toys. He starts off well with each bottle but then seems to hit a wall with it and can't go any further.
If anyone has had similar issues or has any thoughts I could take to my gp, I would be really grateful!! I'm becoming so anxious and worried about the whole thing.
Thank you
